How to replace @SchedulerLock with programmatic style

Question

I use spring boot and somewhere in code I have following code:

@SchedulerLock(name = "onlineIngestionTask", lockAtMostFor = 900, lockAtLeastFor = 900)
    public void pullTasksFromRemote() throws InterruptedException {
        logger.info("task-started");
        Thread.sleep(500);
        logger.info("task-stopped");
    }

Is there way to replace it via programmatic style?

before execute pullTasksFromRemote get lock then release the lock — TongChen, Feb 11 '19 at 10:58

You seem to be able to do it without Spring Annotations like said in the documentation: https://github.com/lukas-krecan/ShedLock#running-without-spring

LockingTaskExecutor executor = new DefaultLockingTaskExecutor(lockProvider);

...

Instant lockAtMostUntil = Instant.now().plusSeconds(600);
executor.executeWithLock(runnable, new LockConfiguration("lockName", lockAtMostUntil));

in documentation said "without Spring" Annotations not mentioned – gstackoverflow Feb 11 '19 at 11:03
He is using Shedlock. His question is tagged with it. – Michael Feb 11 '19 at 11:03
@gstackoverflow What do you mean? "Without Spring" and "without annotations" are, in this case, exactly the same thing. – Michael Feb 11 '19 at 11:04
@Michael,I didn't understand differents in semantics just pointed out in lexical difference. If it is the same - cool. – gstackoverflow Feb 11 '19 at 11:40
@Michael , what is default lockProvider ? – gstackoverflow Feb 11 '19 at 21:43
@gstackoverflow All the providers are [here](https://github.com/lukas-krecan/ShedLock/tree/master/providers). I would guess that the Spring default is probably jdbc. – Michael Feb 12 '19 at 17:27
